Barracuda CloudGen Firewall's customer service is accessible and knowledgeable, though support quality varies due to language and documentation issues.
Sentiment score
6.4
Many users rely on forums for support, expressing mixed satisfaction with OPNsense's accessibility, cost, and technical support.
I would rate their support for FortiGate a nine out of ten.
They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
Barracuda's partner support is better than the majority, and it stands out as one of their strengths.
The overall security has been satisfactory, with no breaches.
The technical support from Barracuda is very good.
I mainly rely on community support since the solution is open source.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiGate offers effective scalability for diverse environments, though hardware upgrades and configuration complexities may arise.
Sentiment score
7.8
Barracuda CloudGen Firewall offers excellent scalability and management for various business sizes, though future capacity planning is advised.
Sentiment score
6.5
OPNsense is scalable for diverse organizations, efficiently supporting different user volumes, with some challenges in high-volume voice traffic.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
When positioning into customers, some larger enterprise customers tend to move towards one of the top three: either Cisco, Fortinet, or Palo Alto.
In my organization, there are 400 users, and OPNsense serves as our gateway and proxy for all of them.
Aside from these aspects, it demonstrated good scalability.
It supports routing, VPN setups, and traffic monitoring with additional packages like Snort and Suricata.
 

Stability Issues

Sentiment score
7.9
Fortinet FortiGate is generally stable and reliable, with most issues being resolved through updates and proper setup.
Sentiment score
8.2
Barracuda CloudGen Firewall is highly reliable and stable, with effective support and improved performance, despite minor bugs and past issues.
Sentiment score
8.5
OPNsense is stable with high ratings, despite issues with VPN failover, occasional bugs, and hardware compatibility concerns.
We have not had any problems with the operating systems or maintenance of subscriptions.
The solution is very stable.
We have observed that the device is significantly more stable than before.
We have very few issues with Barracuda Firewall, even in the case of zero-day vulnerabilities.
Version 8.0 had issues, but the newer version 9.0 seems to have improved performance regarding these issues.
Stability-wise, I rate the solution a ten out of ten.
It just doesn't respond, so I have to restart it over and over again to try to figure out what the problem is.
OPNsense is the same, but it does have a way of installing the Realtek drivers, which gives you a lot more stability overall on the system.
 

Room For Improvement

Fortinet FortiGate needs better documentation, user experience, scalability, and competitive features, with improvements in support, pricing, and security.
Barracuda CloudGen Firewall suffers from complex usability, unclear manuals, limited reporting, challenging licensing, high pricing, and VPN issues.
OPNsense faces challenges with integration, user interface, documentation, scalability, performance, and security features, needing enhancements in various areas.
If I have put 10 GBPS of throughput on a firewall and I enable all of these features available, such as IPS or UTM functionalities, the throughput comes down to 1 GBPS.
By providing an integrated solution, users would have access to all features and functionalities within a single window, eliminating the need to navigate through multiple windows.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
Integration with AI would be helpful as modern attacks often utilize AI.
It would be beneficial to merge the existing application policy with the main policy into a single unified policy to improve manageability.
Some licensing aspects are challenging; for example, if you're using an active-passive setup, you have to license both firewalls.
For high availability, it's crucial to have a method in place where a designated component oversees the entire process.
The user experience when we create policies can be made easier.
Some of the features include classified traffic and better blocking of newly registered DNS domains.
 

Setup Cost

Enterprise buyers find Fortinet FortiGate competitively priced, offering flexible licensing, though some find renewal costs and licensing complexity challenging.
Barracuda CloudGen Firewall is cost-effective with transparent licensing, offering significant savings and includes a four-year replacement program.
OPNsense is a cost-effective, flexible solution for enterprises, preferred over costly alternatives like FortiGate and Palo Alto.
The most expensive part is the renewal of the license subscription.
FortiGate is priced lower than Palo Alto.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
The license price of Barracuda CloudGen Firewall is lower than others, and maintenance or support is included.
It is neither the cheapest nor the most expensive option available.
It's a free solution.
It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident.
I would rate the pricing a nine out of ten, especially considering the availability of a free community edition.

Efficient, user-friendly, and affordable
In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Ensures data security with advanced intrusion prevention and 24/7 monitoring
I rate the initial setup as ten out of ten. It is straightforward to set up a CloudGen file, taking a couple of hours. Once we have the configuration agreed with the customer, the setup and onboarding are completed within a few hours. We receive the box from Barracuda or from our stores, pre-stage it into our network for initial configuration and Soak testing to ensure functionality. The customer can install it at their location, or we do it on their behalf. We run the firewall in simulation mode to observe traffic and ensure service transition is effective. After confirming functionality with the customer, we transition to a live service.
Eddy Ramirez - PeerSpot reviewer
Good interface and firewall capabilities and overall easy to use
The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.
